Definitions

  • the invention relates to a door handle assembly for a motor vehicle, having a frame-like handle mounting, an operating handle that is moveably supported on the handle mounting for opening a door or hatch of the motor vehicle by user, a mechanical coupling device, by means of which a movement of the operating handle can be transferred to a vehicle-side closing assembly, and a locking device serving as a mass locking device, which is moveably retained on the handle mounting and is designed such that, with the effect of an acceleration force, it can be moved from a normal operating position, in which an actuation of the operating handle is possible, in a first blocking direction, in which an actuation of the locking assembly by means of the operating handle and/or the coupling device is blocked.
  • Door handle assemblies of this type having a locking device serving as a mass locking device, are intended to prevent the acceleration force occurring in an accident leading to an actuation of the operating handle, or door handle, respectively, and resulting in an unintentional opening of the door of the motor vehicle, which is accompanied by significant risks to a passenger in the motor vehicle.
  • the handle components that are to be actuated by a user are mechanically coupled to a vehicle-side closing assembly (the actual door locking device). The movement of the door handle, or operating handle, respectively, is transferred to the closing assembly by the mechanical coupling device, and the door is allowed to open.
  • DE 199 29 022 C2 describes a mass locking device of this type in the form of a pivotal member, which is intended to block an actuation of the handle in the case of a crash.
  • forces are exerted on a locking member, and an unintended movement of the handle, likewise caused by the forces acting thereon, is blocked.
  • a door handle assembly of the type indicated in the introduction is also known, for example, from DE 10 2009 053 553 A1. With this door handle assembly, an additional force acts on the operating handle, or door handle, respectively, by means of a crash lock, by means of which an unintended movement of the operating handle should be reliably prevented.
  • Crash locks of this type can be designed as a pendulum mass, such that, as a result of the force acting thereon, the crash lock is displaced, for example, into the movement path of the operating handle, thereby blocking the operating handle.
  • crash locks are also known, which catch in a blocking position, and after their activation and catching, can only again be deactivated by means of a targeted intervention in the door handle unit, such that the door handle can again be used in the normal operation.
  • the known locking devices are only active in a relatively small operating displacement range that blocks an actuation of the pivot arm, or operating handle, respectively, such that, either with strong and pronounced oscillations, or with oscillations occurring over a long period of time as a result of the effects of acceleration forces, there is the danger that, with locking devices swinging back and forth, the operating displacement range is not sufficient for reliably preventing a blocking of the operating handle, or pivot arm, respectively. For this reason, the locking device can assume a position in the case of a crash, during the swinging process, despite its activation, in which the operating handle, or the pivot arm, respectively, is not blocked.
  • the invention addresses the objective of creating a solution, which provides a door handle assemble in a simple and cost effective manner, with which the locking device reliably and securely blocks the operating handle, or pivot arm, respectively, even with oscillations resulting from a crash that occur over a long period of time, or are extremely pronounced.
  • the locking device is designed such that it can move, as a result of the effects of an accelerating force, from the normal operating position in a second blocking direction, in which an actuation of the closing assembly by the operating handle and/or the coupling device is blocked, wherein the second blocking direction is opposite the first blocking direction.
  • a door handle assemble for a motor vehicle is provided by the invention, which is distinguished by a functional construction, and has a simple and cost-effective structure.
  • the locking device is designed such that it can move, as the result of the effects of an acceleration force, from the normal operating position, not only in a first blocking direction, but also in a second blocking direction, the field of application for the locking device is increased, because this can now no longer only be activated by an acceleration force acting in a single, predetermined direction, but also by the effects of an acceleration force in a second direction.
  • This property of the locking device is advantageous, in crashes, for example, in which, due to the acceleration forces acting thereon, pronounced oscillation processes prevail, leading to a back and forth swinging of the locking device between a normal operating position and a blocking position.
  • the locking device can also move in a second blocking direction in the case of a crash, the operating handle and/or the coupling device is also effectively blocked during a crash when the locking device swings back, because the locking device moves from a first blocking position, through the normal operating position, in a second blocking direction when it swings back, by means of which the locking device never remains, at any point in time, in the normal operating position, but rather, only passes through the normal operating position.
  • the coupling device has at least one movement projection acting together with the locking device.
  • the movement projection defines precisely the case in which a normal operation of the operating handle is possible, and when not.
  • the invention further provides, in an advantageous design, that the locking device has a movement cavity, into which the movement projection of the coupling device can at least be moved for actuating the operating handle when the locking device is disposed in the normal operating position. This does not exclude the possibility that the movement projection of the coupling device cannot also move completely through the movement cavity.
  • the locking device is designed, at least in sections, as a hollow cylinder, wherein the movement cavity is formed such that it runs, starting at the open front end of the hollow cylinder, in the longitudinal direction thereof.
  • the locking device is designed such that, when the operating handle is not actuated, the movement projection extends into the open front end of the hollow cylinder in the normal operating position, and when the operating handle is actuated, the actuation projection moves through the movement cavity and out of the hollow cylinder, away from the locking device.
  • the locking device can, for reasons of a minimal installation space, be designed, at least in sections, as a disk element, on one lateral surface of which, the movement cavity in the locking device is designed as a guide channel, open on one side, which extends, offset to the center of the disk element, on this lateral surface.
  • the interaction of the coupling device and the locking device is provided for in the above design in a further development of the invention, in that, in the normal operating position of the locking device, the movement projection is disposed outside the guide channel when the operating handle is not actuated, and when the operating handle is actuated, the actuating projection is designed to move into the guide channel.
  • the locking device is rotatably supported on the handle mounting by means of a pivot axle, and when the movement of the locking device in the first or second blocking direction is a rotational movement of the locking device.
  • the minimal installation space is further benefitted as a result, in that, in another design of the invention, it is provided that the pivot axle of the locking device is rotatably supported at its center.
  • the invention provides, in a further design, that the locking device can rotate about the pivot axle at least ⁇ 90°, preferably ⁇ 285° from the normal operating position, due to the effects of an acceleration force.
  • This rotational path, or swinging path, respectively, with the activation of the locking device is sufficiently large enough that the crash state, which occurs as a result of the effects of the acceleration forces in conjunction with the oscillations to the vehicle structure generated thereby, comes to an end, before the locking device is again returned to where it rests in the normal operating position because of its spring tension.
  • the invention provides that the locking device has a mass weight, which is disposed such that it is offset to the pivot axle on the locking device. The acceleration forces interact with this mass weight, and ensure that the locking device, when activated, rotates about the pivot axle in the first or second blocking direction.
  • the invention provides, in an advantageous design, that the coupling device is rotatably supported about a point of rotation on the handle mounting, wherein the pivot axle of the locking device is oriented such that it is substantially transverse to the point of rotation of the coupling device.
  • the invention provides, in one design, that the coupling device is rotatably supported about a point of rotation on the handle mounting, wherein the pivot axle of the locking device is oriented such that it is substantially parallel to the point of rotation of the coupling device.
  • a mechanical return element which exerts a force that forces the locking device into the normal operating position.
  • the operating handle can thus be used and actuated again after the effects of acceleration forces, because the locking device is again located in the normal operating position.
  • the mechanical return element comprises an elastic spring element, which is supported against both a projection that is fixed in place on the handle mounting, as well as against a contact surface that moves together with the locking element, wherein the contact surface moves in relation to the projection, against the force of the elastic spring element, when the locking device moves in the first or second blocking direction.
  • the invention provides, in one design, that the mechanical return element is configured such that it retains the locking device in the normal operating position, until an acceleration force has reached at least 7 g.
  • the locking device is only activated by a greater acceleration force, and rotates in the direction of the first or second blocking direction, and oscillates in these two directions, without remaining thereby in the normal operating position, such that an actuation of the operating handle is effectively blocked.
  • This threshold value is sufficient for preventing an unintended activation of the locking device, and thus its deflection.

  • the locking device 8 ′ is rotated ⁇ 285° about the pivot axle 18 ′ (Z axis) as the result of the effects of an acceleration force in the first blocking direction 21 (see arrow 21 in FIG.
  • the locking device 8 ′ is rotated +285° about the pivot axle (Z axis) as a result of the effects of an acceleration force, or as a result of a swinging movement, in the second blocking direction 22 (see arrow 22 in FIG. 18 ), by means of which the guide channel 24 , or the movement cavity 15 ′, respectively, is then no longer in the movement path of the movement projection 14 ′.
  • FIGS. 17 and 8 An actuation of the operating handle 4 or a pivoting of the coupling device 7 ′, which is rotatably supported on the handle mounting 6 , such that it can rotate about its axle journals 11 , is then blocked in FIGS. 17 and 8 as a result of the rotation of the locking device 8 ′ about the pivot axle 18 ′, because the movement projection 14 ′ can no longer enter the guide channel 24 , or move into this guide channel, respectively, due to the rotation of the coupling device 7 ′. Instead, the movement projection 14 ′ hits a contact surface 25 , having the shape of a segment of a circle, which is formed on the lateral surface of the disk-shaped locking device 8 ′ lying opposite the mass 19 .
  • the pivot axle 18 ′ of the locking device 8 ′ is oriented substantially parallel to the point of rotation 20 of the coupling device 7 ′, in order to obtain the desired blocking of the operating handle 4 , or the coupling device 7 ′, when acted on by an acceleration force.
  • a smaller rotational angle is also conceivable.
  • the mechanical return element 26 (see FIGS. 3 and 11 , by way of example) exerts a force that forces the locking device 8 , 8 ′ into the normal operating position, such that this does not presently concern a locking device that locks in position, but rather, it concerns a locking device that returns to its starting position.
  • the mechanical return element 26 can comprise an elastic spring element 27 , as is depicted in the two embodiments.
  • the respective spring element 27 is supported at both ends, on both a projection 28 of the handle mounting 6 , that is fixed in place, as well as on a contact surface 29 that moves together with the locking element 8 , 8 ′ (see FIGS. 5 and 14 ).
  • the contact surface 29 moves in relation to the projection 28 against the force of the elastic spring element 27 , in that one of the two ends of the spring element 27 is deflected.
  • the mechanical return element 26 , or the spring element 27 is designed such that it retains the locking device 8 , 8 ′ in the normal operating position, until an acceleration force of at least 7 g has been applied.
  • a door handle assembly 3 , 3 ′ having a non-locking locking device 8 , 8 ′ is provided, which is distinguished by a secure activation, and which securely blocks the operating handle 4 , or the coupling device 7 , 7 ′, respectively, even with oscillations resulting form the effects of acceleration forces.
  • This is enabled according to the invention in that the locking device 8 , 8 ′ can rotate at least ⁇ 90° about its pivot axle 18 , 18 ′, such that swinging movements in both directions, i.e. rotational movements in opposite directions, by the locking device 8 , 8 ′ are possible.
  • the path for the deflection of the locking device, in order to move it into the movement path of the coupling device is too small, which leads to situations in practice, in which the locking device moves back, after its deflection, as a result of oscillations, in an abrupt manner, and the coupling device is not blocked at times, which leads to an undesired actuation of the closing assembly and opening of the door.
  • This danger is no longer present with the present invention, because the locking device 8 , 8 ′ has a greater path to travel when activated, which is defined by the rotational movement as at least 90° about the pivot axle 18 , 18 ′.
  • the locking device 8 , 8 ′ can move in two opposing blocking directions, such that a blocking of the operating handle 4 , or the coupling device 7 , 7 ′, respectively, is provided, even during a swinging of the locking device 8 , 8 ′ in both directions.
  • the pivot axle 18 of the locking device 8 is oriented substantially transverse to the point of rotation 20 of the coupling device 7
  • the pivot axle 18 ′ of the locking device 8 ′ is oriented substantially parallel to the point of rotation 20 of the coupling device 7 ′.
